植物乙醇提取物对荔枝蒂蛀虫成虫产卵的影响

EFFECTS OF PLANT SEMI-CHEMICAL ON DETERRING THE EGG LAYING OF ADULTS OF CONOPOMORPHA SINENSIS BRADLEY

本文应用干扰作用控制指数 (IIPC)评价了 2 4种植物异源植物次生物质对荔枝蒂蛀虫成虫产卵的影响 ,结果表明 :在供试的 2 4种植物乙醇提取物中 ,对荔枝蒂蛀虫成虫产卵干扰作用效果较好的有非洲山毛豆Tephrosia vogelli、飞机草 Eupatorium odoratum、大叶桉 Eucalyptus robusta的乙醇提取物 ,其 IIPC值分别为0 .10 94、0 .112 2、0 .12 74 ,即它们对荔枝蒂蛀虫成虫产卵的驱避作用效果在 80 %- 90 %之间。

In the paper, the interference indices of population control (IIPC) were used to evaluate the effects of spraying alcohol extracts of the non preferable plants on deterring the egg laying of adults of Conopomorpha sinensis Bradley. The results showed that the alcohol extracts of Tephrosia vogelli, Eupatorium odoratum, Eucalyptus robusta gave noticeable effect to protect the plant against Conopomorpha sinensis Bradley. The IIPC of these extracts were 0.1094?0.1122?0.1274, respectively. It means that the effects of these extracts were between 80% and 90%. These extracts maybe used as repellents to construct the cruciferous plant protectant.
